BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of NewGuinea Impatiens plant, botanically known as Impatiens×hybrida andhereinafter referred to by the name ‘Duesspneon’.

The new Impatiens plant is a product of a planned breeding programconducted by the Inventor in Encinitas, Calif. The objective of thebreeding program is to create new uniform Impatiens plants with numerousattractive flowers and good garden performance.

The new Impatiens plant is a naturally-occurring whole plant mutation ofa proprietary selection of Impatiens×hybrida identified as code numberNN-1165-X0000, not patented. The new Impatiens plant was discovered andselected by the Inventor as a single flowering plant from within apopulation of plants of the parent selection in a controlled greenhouseenvironment in Encinitas, Calif. on Dec. 8, 2014.

Asexual reproduction of the new Impatiens plant by terminal vegetativecuttings in a controlled greenhouse environment in Encinitas, Calif.since Jan. 9, 2015 has shown that the unique features of this newImpatiens plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duesspneon’. These characteristics incombination distinguish ‘Duesspneon’ as a new and distinct Impatiensplant:

-   -   1. Upright, outwardly spreading and mounding plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit.    -   4. Dark green-colored leaves.    -   5. Early and freely flowering habit.    -   6. Cerise-colored flowers.    -   7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the parentselection. Plants of the new Impatiens differ primarily from plants ofthe parent selection in flower color as plants of the parent selectionhave dark salmon-colored flowers with coral-colored tones.

Plants of the new Impatiens can be compared to plants ofImpatiens×hybrida ‘Duessprosaur’, disclosed in a U.S. Plant Patentapplication filed concurrently, having application Ser. No. 14/756,455.Plants of the new Impatiens differ primarily from plants of‘Duessprosaur’ in flower color as plants of ‘Duessprosaur’ have rosepink-colored flowers.

Plants of the new Impatiens can be compared to plants ofImpatiens×hybrida ‘SAKIMPOO9’, disclosed in U.S. Plant Pat. No. 19,622.In side-by-side comparisons conducted in Encinitas, Calif., plants ofthe new Impatiens differed primarily from plants of ‘SAKIMPOO9’ in thefollowing characteristics:

-   -   1. Plants of the new Impatiens were more compact than plants of        ‘SAKIMPOO9’.    -   2. Plants of the new Impatiens and ‘SAKIMPOO9’ differed in        flower color as plants of ‘SAKIMPOO9’ have red-colored flowers        with red purple-colored centers.

Plants of the new Impatiens can also be compared to plants ofImpatiens×hybrida ‘Misato FG3’, disclosed in U.S. Plant Pat. No. 17,662.In side-by-side comparisons conducted in Encinitas, Calif., plants ofthe new Impatiens differed primarily from plants of ‘Misato FG3’ in thefollowing characteristics:

-   -   1. Plants of the new Impatiens were more compact than plants of        ‘Misato FG3’.    -   2. Plants of the new Impatiens and ‘Misato FG3’ differed in        flower color as plants of ‘Misato FG3’ have magenta-colored        flowers.
